In particular, the home location register 150 stores profile information including the phone number (MSISDN), IMSI, subscribed additional services, etc. of the wireless communication terminals 110 and 120.

The wireless communication terminals 110 and 120 may make video calls with each other using the above components. In addition, when the video communication call is received and the call connection signal is input from the user, the wireless communication terminals 110 and 120 set up the video call through the speaker before the channel and codec negotiation is completed (that is, before the video call is performed). Outputs a message to the speaker indicating that it is busy and displays it on the screen.

More specifically, the wireless communication terminals 110 and 120 operate a vibration motor or a ringing sound when a video call is received, and receive a call connection signal from a user who recognizes the call. Try. In the connection process, the wireless communication terminals 110 and 120 proceed with channel and codec negotiation with the calling terminal requesting the video call. Before the completion of the negotiation, the wireless communication terminals 110 and 120 inform that the video call is being set up. Is output through the speaker and displayed on the screen to allow the user to recognize that the channel and codec negotiation for the video call connection is in progress.

2 is a diagram illustrating a configuration of a wireless communication terminal that outputs a message indicating that a video call is being set up according to an embodiment of the present invention.

As shown in FIG. 2, the wireless communication terminals 110 and 120 outputting a message indicating that the video call is being set up according to an embodiment of the present invention are the communication unit 210, the memory 220, the display unit 230, and the input unit ( 240, the handset 250, the camera 260, and the controller 270.

The communication unit 210 connects to the base station 130 of the mobile communication system and performs a function of transmitting / receiving and communicating with a radio signal. The communication unit 210 communicates with the base station through a pilot channel, paging channel, traffic channel, and the like.

The memory 220 includes an electrically erasable and programmable read only memory (EEPROM), a flash memory, and the like, and stores a phone book, a schedule, a picture, a video, a recent call list, and the like. In particular, the memory 220 includes a sound source for notifying that the video call is being set.

The display unit 230 provides the user with information processed by the wireless communication terminals 110 and 120. The display unit 230 is a liquid crystal display for displaying the processing state of the wireless communication terminal (110, 120) on the screen, a light emitting lamp for transmitting information through the light emission of the light emitting element, vibration for transmitting information through the vibration of the vibration motor Device and the like.

The input unit 240 receives a signal for operating the wireless communication terminals 110 and 120 from a user by using an input means such as a keypad and transmits the signal to the controller 270.

The handset 250 includes a speaker for outputting sound and a microphone for receiving a voice signal from a user.

When a video call is received from the communication unit 210 and a call connection signal such as a call button manipulation, a folder open, or a slide open is input through the input unit 240, the video call setting notification unit 270a may display an image in the memory 220. It extracts the sound source indicating that the call is being set and outputs it through the speaker. When the sound source for notifying the video call is not set, the video call setting notification unit 270a extracts the sound source set as a default from the memory 220 and outputs the sound source to the speaker. An example of the sound source set as the default is as follows: "The screen is being adjusted for video call connection."

Hereinafter, a description will be given on the assumption that the calling terminal is 110 in FIG. 1 and the called terminal is 120 in FIG. 2.

3 is a flowchart illustrating a method of outputting a notification message when a video call is set up according to an embodiment of the present invention.

Referring to FIG. 3, the calling terminal 110 attempts a video call to the called terminal 120 (S301). At this time, the originating terminal 110 transmits to the originating exchange a setup message in which Unrestricted Digital Information (UDI) is set to perform a video call. The setup message means information of performing a video call using the international standard H.324M protocol. The H.324M protocol includes H.245 and H.223 protocols, and since the protocol is already designated as an international standard, detailed description thereof will be omitted.

The originating exchange receiving the setup message from the originating terminal 110 sends the routing information (SRI: Send Routing Information) of the called exchange to the home location register 160 to set up the video call to the terminating terminal 120. The profile information of the called terminal 120 is requested (S303). Subsequently, the originating exchange transmits a message (Call Proceeding) indicating that the video call is being set up to the originating terminal 110. If the call (Call Proceeding) is not received for a certain time, the calling terminal 110 determines that the setup message is not normally transmitted to the calling exchange and stops the video call transmission.

Upon receiving the SRI request from the originating exchange, the home location register 160 requests a destination routing number (PRN) to the destination exchange to receive it (S305 and S307). Receiving a response to the routing number providing request from the destination exchange, the home location register 160 transmits the routing information SRI of the destination exchange and the profile of the destination terminal 120 to the originating exchange (S309). Subsequently, the originating exchange transmits an IAM (Initial Address Message) including the called terminal identifier to the called exchange and requests call establishment with the called terminal 120 (S311).

The destination exchange receiving the call establishment request with the destination terminal 120 determines the location of the destination terminal 120 by transmitting a paging signal to the destination terminal 120 through the base station 130 and receiving a response accordingly. Subsequently, the destination exchange transmits a setup message to the destination terminal 120 and receives a call confirmation message corresponding thereto (S313 and S315).

The terminating terminal 120 transmits an allerting message informing of the call waiting state to the terminating exchange (S317). At this time, the terminating terminal 120 outputs an incoming call notification signal such as a ring tone or a vibration motor so that the called party can recognize that the call has been received. Subsequently, the destination exchange transmits an address complete message (ACM) to the originating exchange, and the originating exchange transmits an allerting message indicating that the terminating terminal 120 is in a call waiting state to the originating terminal 110 (S319, S321). At this time, the caller listens to the ringback tone, and recognizes that the video call transmission signal is connected to the called terminal 120. The ringback tone tone is output from the originating exchange or the terminating exchange and transmitted to the originating terminal 110.

The destination terminal 120 receives a call connection signal such as a call button operation, a folder open, a slide open, and the like that attempts to make a call connection with the caller from the user (S323). Then, the terminating terminal 120 transmits a Connect message to the terminating exchange and outputs a message indicating that the video call is being set up through a speaker and displays it on the display unit 230 (S325 and S327). The message informing that the video call is output to the speaker is being set may be a specific sound source specified by the user.

Subsequently, the destination exchange transmits a Connect Ack message indicating that the connection message has been normally received to the destination terminal 120, and the destination exchange transmits an Answer Message (ANM) to the originating exchange (S329). ). The originating exchange transmits a connect message to the originating terminal 110 and receives a connection acknowledgment message from the originating terminal 110 (S331).

The originating terminal 110 receiving the Connect message proceeds with the destination terminal 120 and the channel negotiation and codec negotiation according to the H.324M standard, and when the negotiation is completed, the destination terminal 120 and the originating terminal ( A video channel is formed between 110 and a video call proceeds (S333, S335). Meanwhile, in step S327, the message indicating that the video call is being established is preferably output to the speaker continuously (or at regular intervals) until the channel and codec negotiation is completed.

4 is a flowchart illustrating a method of outputting a video call notification message in a wireless communication terminal according to an embodiment of the present invention.

Referring to FIG. 4, when the incoming terminal 120 receives a video call, the incoming terminal 120 operates a ring tone, a vibration motor, a light emitting lamp, and the like to recognize the incoming call to the user (S401). The receiving terminal 120 receives a call connection signal such as a call button operation, a folder open, or a slide open from the user (S403). Then, the receiving terminal 120 checks whether there is a sound source for notifying that the user is setting the video call previously set (S405). The sound source indicating that the video call is being set may be an effect sound, a recorded voice of a user, a melody, and the like.

If there is a sound source indicating that the video call is set by the user, the called terminal 120 extracts the sound source and outputs it through a speaker (S407). On the other hand, if a sound source notifying that the user is setting the video call is not set, the destination terminal 120 outputs a sound source indicating that the video call is set by default (S409). An example of the sound source set as the default is as follows: "The screen is being adjusted for video call connection." In addition, when the sound source indicating that the video call is being set is output, the called terminal 120 may output a message indicating that the video call is being connected to the display unit 230.

Subsequently, the called terminal 120 proceeds with channel and codec negotiation with the calling terminal 110 which has requested the video call, and when the negotiation is completed, forms a channel to proceed with video calling with the calling terminal 110 (S411).

Through the above-described method, even if the user receives a video call and inputs a call connection signal and reflects it to the ear, the call is transmitted due to a sound source indicating that the video call is being output to the speaker of the wireless communication terminals 110 and 120. You will notice that it is a video call.

The method of the present invention as described above may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
